I was over in Amsterdam one day and decided to go visit Chakuriki, not to train but just to watch their training. I was greeted by Thom Harinck, who was about to start his class.
This tall lanky guy starts to beat the ever living crap out of a boxing bag, it was quite a sight. He then enters the ring and the pure violence he would unleash on his opponents was unreal. At one point he was sparring his own cousin, if I remember correctly, and I wouldn't bw surprised if the kid was pissing blood afterwards. Those body shots were brutal. I don't think anyone got out of that ring without being knocked down.
As you might have guessed, the tall lanky kid was a 20- year old Badr Hari. The delight he took in punishing people in training coupled with his talent was seriously scary.
